Product Description
Vibration Resistance Φ2.3mm Tungsten Carbide Products with Enhanced Durability and Polished Grinding Surface
Φ 2.3mm Solder Core Vibration Resistance Tungsten Carbide Products
The tungsten carbide nozzle designed for 1500-2000μm solder balls features an extremely thin wall thickness of 0.5mm (depth-to-diameter ratio of 1.43). This design overcomes deformation and cracking challenges in large-aperture nozzles, enabling zero-spatter precision spraying under high heat load conditions in electric vehicle and industrial power supply welding applications.
Processing Difficulties and Solutions
-
Thin-wall sintering deformation control:
- Wall thickness: 0.5mm (outer diameter 3.3mm/inner diameter 2.3mm)
- SPS gradient sintering temperature control ±3℃ (suppresses ellipticity deviation) -
Deep hole mirror polishing:
- Inner hole depth-to-diameter ratio: 1.43 (Ra≤0.2μm)
- Customized diamond reamer (feed rate 0.5μm/rpm) -
Coaxiality precision:
- Inner/outer circle coaxiality: ±0.005mm (3* higher than national standard G grade)
- Industrial CT online correction (resolution 2μm) -
Thermal stress cracking prevention:
- Cobalt phase gradient strengthening (reduces interface stress by 40%)
- Pulse electrolytic sharp edge treatment (eliminates corner collapse risk)
